Factual error: When the elevator falls to the ground it passes a hotel waitress and blows her hair and pieces from her trolley away. In fact the wind gust comes after the elevator has passed, in reality it would come before it passed, as the air ahead of the elevator would be compressed and blown outwards, leaving lower pressure behind which would cause a gust inwards.
Factual error: When the elevator falls to the ground, it is in free fall. The cop lying on top of it should lift away from it as it falls, but doesn't.
